DeaR ComRades, This is a quote from a News article in Science's 11-February issue, about competitions to model data: "For Chris Raimondi, a search-engine expert based in Baltimore, Maryland, and winner of the HIV-treatment competition, the Kaggle contest motivated him to hone his skills in a newly learned computer language called R, which he used to encode the winning data model. Raimondi also enjoys the competitive aspect of Kaggle challenges: "It was nice to be able to compare yourself with others; ... it became kind of addictive. ....

Hello, I'm the maintainer of a syntax highlighting tool highlight.js[1]. Recently the Kaggle project has announced they wanted to sponsor the development of the R highlighting definition for it[2]. I wanted to drop a line about it here since I suspect this list has much more R programmers on it than our small discussion group :-). So if you're interested and don't mind touchin...

Un offtopic para empezar el fin de semana. Acabo de entrar en kaggle, hacia tiempo que no lo hacia, y veo con 'estupor' que practicamente la gente trabaja con python.

Hello Everyone! It's been a while since I last posted a question! Hope everyone has been doing well! ~~~ CONTEXT ~~~ I have recently entered a beginner-level competition on kaggle. The goal of the competition is to build a model that predicts who did/did not survive on the Titanic. I decided to use random forests as I have been wanting to learn the algorithm and the competition was the perfect impetus. Unfortunately, the model I have built is not very accurate. ~~~...

Using caret on the Titanic data from Kaggle, I tried various models, including rfRules which produces a model, partly described as such: > caret.rfRules.cv$finalModel $model len freq err [1,] "2" "0.0368" "0" [2,] "2" "0.032" &quo...

Gracias Ruben, muy interesante. Algo así estuve buscando, por ciudades y a nivel internacional, pero no lo encontré. Me bastaría con el número de fallecimientos por día, de cuantas más ciudades del mundo mejor. Si alguno supiera de algo así, le agradecería que me lo comunicase.

...d by xapian-letor. To train a click model, we'd need a relevance prediction dataset that should contain human generated binary relevance labels for query-document pairs. I'm curious to know from where we can obtain such a dataset. One that I know of is Yandex web seach challenge dataset on Kaggle. And, thanks for the link to MSet re-ordering system. I'll check out ideas that were discussed there. > That page is ancient, so I hope you're actually installing the 1.4 series > Xapian and Omega!
